Inside History on Instagram: "Greyhounds are one of the fastest dog breeds in the world, designed for explosive speed and short-distance endurance. Capable of sprinting up to 72 km/h (45 mph), their speed comes from a unique combination of long legs, a flexible spine, a deep chest, and a lean, muscular build. These physical traits make them exceptional at racing and coursing, where rapid acceleration and sustained bursts of speed are essential! #history #reels #explore #viral #trending"
